L FOR "WASTES AND OVEBFLOWS.

Specification of Letters Patent.

Patented July 22, 1913.

Application filed July 10, 1912. Serial No. 708,586.

To all whom it may concern Be it known that 1, ROBERT CLARK, a citi; zen of the United States, residing in Bridgeport, county of Fairfield, and State of Connecticut, have invented certain new and useful Improvements in Us for l Vastes and Overflows, of which the following isa full, ear, and exact description.

This invention relates to l.s for bath tub or other fittings.

The primary object of the invention is to provide an improved form of sheet metal l. for use in a combined waste and overflow or in other applicationsor connections.

The improvements relate particularly to the provision of means on the l. for centering it accurately in the hole or aperture in a bath tub or other part, in order to insure a proper assemblage of the parts and to facilitate the mounting or assemblage of the fixture.

It is also proposed to provide the L, for

example, the overflow L, with a device which not only centers the l. in the opening pre pared for it but also supports and centers the gasket or washer which is to be interposed between the l. and the tub wall.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawing, Figure 1 is a side elevation of a fixture embodying my invention showing it applied to a bath tub, the bath tub being shown in section. Fig. 2 is an enlarged sectional view ofthe overflow L, corresponding to Fig. 1, Fig. 3 is a side elevation of the overflow l. detached from the tub, and Fig. 4 is a front or face view of the overflow l...

Referring to the drawing, the fixture which I have illustrated is of the well known combined waste and overflow type, comprising a waste 5. 5, a waste pipe 6, a "l' 7, an overflow l. 8, and overflow pi'pe'9, and a common outlet pipe 10. These parts are shown in Fig. l, as applied to a bath tub 11.

As shown my invention resides in certain improvements in connection with the overflow l. 8, although it will be understood that the improvements are not necessarily limited to use in an overflow or in a coin bined waste and overflow.

According to invention 1 provide an 3.. of sheet metal having annular front plate 12 secured in the mouth of the l. by means of a flange or bead 13 at the margin of the L mouth, spun over the edge of said annular plate, as shown in Fig. 2. The plate 12 is also formed of sheet metal and it is providedwith an integral stamped bridge 14 extending diametrically across it and bulged to a slight extent forwardly of the plane of the body of the plate 12. This bridge is braced and strengthened considerably against buckling, by means of ribs 15 formed by indenting one face of the bridge, as shown in Fig. 4. At the center of the bridge the same is provided with a threaded socket 16. On opposite sides of the bridge 14, the plate 12 is provided with comparatively long arcuate centering flanges 17 and 18, struck up integrally from the plate at the inner periphery ofthe same and extending forwardly of the L to a considerable extent,

as shown in Fig. 2. The arcs of the (Lenten ing flanges have a common center corresponding withthe center of the bridge 14.- andof the socket 16, and they are therefore adapted to conform to and fit properly within a circular opening of proper dimensions in the Wall of the tub, as shown in Fig. 2, thereby effectively centering the l. in the position in which it is to be secured. Before the centcringflanges are placed'in the openingof the tub wall a gasket 19 ofsuitable dimensions is placed over said centering flanges in a position to seat against the tub wall at one face and against the front of the L at the other face. The interiordiameter of the gasket will preferably correspond approximately to the outside diameter of the circle coincident with the outer surfaces of the centering flanges, so that after the gasket has been slipped over the centering flanges, it will be held thereon by friction. The flanges are preferably considerably wider than the gasket so as to extend completely through the tub wall. After the L has been placed in the opening in the tub,

with the gasket in place on the centering member formedby .the flanges ii", 18, the ordinary strainer 20 is applied by means of a screw 21 engaged with the socket 16 in the bridge 14, as shown in Fig. 2. The screw :21 is screwed into the bridge 1+2 until the front face of the l... is squeezed up tight against the gasket 19, and until the gasket 15) in turn is squeezed up tight against the rear surface of the tub wall. The inner face of the strainer 20 is preferably provided near the periphery of the strainer with an annular bead 22 to seat against the front edges of the centering flanges 17 and 18.

The construction described has the advantage that the centering deviceformed by the flanges 17, 18, not only centers the L accurately in the hole in the tub, but also supports and centers the gasket, thereby serving a double function. As a result, the L will beaccurately positioned and a nonleakable joint between it and the tub will be provided.

As previously intimated, my invention is not limited in all its aspects to an overflow. L having a bridge for supporting or attaching a strainer, inasmuch as my improvements are also equally applicable to waste Us and Us used for still other purposes. Moreover, itwill be understood that I do not limit myself to the provision of two relatively long centering flanges, as the number of flanges used may be varied to suit the purpose of the L and other conditions.

What- I claim is:

1. An L comprising a body portion, and a separate sheet metal plate set in the mouth of said body portion and provided with an integral forwardly extending centering flange; substantially as described.

2. An L comprising a body portion, and a separate substantially annular sheet metal plate set in the mouth of said body portion and having a centering flange projecting from the inner periphery thereof; substantially as described.

3. An L comprising a body portion, an

annular plate secured to the mouth of said body portion, a bridge formed integrally with said plate, and forwardly projecting centering flanges struck up from said plate at the inner periphery of the latter on'opposite sides of said bridge; substantially as described.

.4. An L comprising a hollow body portion having a mouth, a separate flat substantially annular plate of sheet metal overlying the mouth of said body portion and extending inward from the rim thereof, a flanged joint connecting the outer periphery of said plate .with the rim of said body portion, and a forwardly extendifig curved centering flange struck up from the inner periphery of said plate and defining an opening communicating with the interior of said body portion:

substantially as described.

5. An L comprising a hollow body portion having a mouth, a separate substantially annular plate of sheet metal' overlying the mouth of said body portion and extending inward from the rim thereof, a flanged joint connecting the outer periphery of said plate with the rim of said body portion, a bridge integral with said plate extending transversely across said. mouth, and centering flanges struck up from the inner periphery of said plate at opposite sides of said bridge substantially as described. 7

In Witness whereof, I have hereunto set my hand on the 9th'day of July, 1912.
